Reggie Yates, Can You Help

I like the simple look Reggie was carrying off on The Voice last night but want to find plain t-shirts, Marl or Pocket style to go underneath blazer. Problem is t-shirts from topman, h&m, river island dont fit regardless of size and american apparel ones tend to deform after being worn once. And dont want All Saints.

I have been looking before now (difficult with sales) found one in this link but wanted other ideas that arent necessarily high street : Cloak & Dagger Black Marl Tee

Can anyone suggest affordable (below £50) but stylish other versions similar to one below??????????

(site wont let me upload the reggie pic i took so had to use example below)
